Abstract (en)

[origin: EP0935264A1] Typically three annular secondary coils (15,16,17) are placed over a central tube (11) so they stack on top of each other, and are strapped in place. The tube sits inside a sealed enclosure, having its two end faces (20,21) constructed with flanges to fasten to the tube and provide a gas tight seal. One end face also has an insulating gasket (31) on its outer edges to isolate it from the remainder of the enclosure.
